Any trouble shooting suggestions for this? After several days of the 6300 working well on a Win 7 i7 laptop and connected to LAN via a Ethernet cable from 6300 to router, today the 6300 "lost contact" with the network. I rebooted the 6300 and SmartSDR and it was briefly "available" but disappeared before I could click on "connect". I then rebooted the laptop, everything was fine for about 30 seconds as SmartSDR connected and showed signals, then the loss of contact message was displayed again. I have now switched to connection directly to the PC and all appears stable. The network connection when I was briefly connected to the LAN was "excellent". Router switching IP addresses all of a sudden , perhaps ?
